[0068] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0069] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "inner," and "outer" in the terminology represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0070] like Figure 1-6 As shown, the present invention provides an automatic high-speed vehicle malfunction warning device, the device comprising: several sets of warning trolleys 7 and a charging and storage box 2 installed on a high-speed guardrail 4; the charging and storage box 2 is used for storing, protecting, and charging the incoming warning trolleys 7, and the several sets of warning trolleys 7 can be connected in a row; wherein,

[0071] Each warning trolley 7 includes: a trolley base 701 with several electric casters 702 at the bottom, a support column 709 vertically mounted on the trolley base 701, and an adjustment plate 705; the top of the support column 709 is hinged to the two opposite sides of the top, and the support column 709 is provided with a drive mechanism for driving the two adjustment plates 705 to open and close to adjust the angle between them and the side of the support column 709; the adjustment plates 705 are connected to the side of the support column 709 by airbags 706 around their perimeter; the trolley base 701 is provided with an inflation pump 714 and an air deflation pump 718 connected to the airbags 706 through a conduit 711; the top of the support column 709 is also provided with a warning light 707.

[0072] In the above scheme, an automatic vehicle malfunction warning device is installed at intervals along the highway guardrail 4 on the highway. After an accident is detected, the nearest automatic vehicle malfunction warning device is activated based on the location of the accident. Specifically, the electric omnidirectional wheel 702 is controlled to move along a prescribed route to move the warning trolley 7 to the designated position. Then, the two adjusting plates 705 are opened by the drive mechanism to unfold the airbag 706. The airbag 706 is then inflated by the air pump 714 to fill it completely. Finally, the warning light 707 is turned on to achieve the warning effect.

[0073] In a preferred embodiment of the present invention, the front and rear sides of the vehicle body base 701 are respectively provided with stabilizing plates 719 by means of rotating shafts arranged along their own length direction, and the ends of the rotating shafts are provided with rotating drivers to drive the stabilizing plates 719 to abut against the ground on the side away from the rotating shafts.

[0074] In the above scheme, several warning trolleys 7 are controlled to move to a designated position, and then the rotating driver is used to drive the stabilizing plate 719 to rest against the ground on the side away from the rotating shaft. This can improve the stability of the warning trolleys 7. With the help of inflated airbags, if a car still accidentally crashes into it under the warning environment, on the one hand, a row of inflated airbags can play a certain buffering protection role, and on the other hand, the warning trolleys 7 also have a certain protection effect. Under the action of the stabilizing plate 719, the warning trolleys 7 can play a double buffering effect, which further improves the safety after the collision to a certain extent.

[0075] In a preferred embodiment of the present invention, the driving mechanism includes: a support rod 710, a threaded rod 716, a threaded slide block 717, and a drive motor 713; the threaded rod 716 is vertically and rotatably disposed within the support column 709, the threaded slide block 717 is threadedly fitted onto the threaded rod 716, and its opposite sides are slidably disposed in vertical sliding grooves formed inside the support column 709 via sliders, the opposite sides of the threaded slide block 717 are respectively hinged to the support rod 710, and the other end of the support rod 710 is respectively hinged to the corresponding adjusting plate 705 to drive the adjusting plate 705 to open and close, and the side of the support column 709 is provided with a clearance groove adapted to the support rod 710.

[0076] In the above scheme, the drive motor 713 drives the threaded rod 716 to rotate in the forward or reverse direction. With the cooperation of the vertical slide groove, the threaded slide block 717 can rise and fall along the length of the threaded rod 716. In this way, one end of the support rod 710 will also rise and fall with the rise and fall of the threaded slide block 717, and the other end can drive the adjustment plate 705 to open and close. When the warning operation is performed, it is opened, so that the permanent magnet strips on the adjustment plates 705 of the two adjacent trolleys will be attracted and fixed together to ensure the stability and integrity of the row of warning trolleys. On the one hand, it expands the warning area, and on the other hand, it can increase the stopping and buffering protection effect on vehicles or people. When not in use, the adjustment plate 705 is driven to close to reduce the overall volume of the warning trolleys, so as to facilitate storage in the charging and storage box for storage and charging operations.

[0077] In a preferred embodiment of the present invention, a trolley control module 715 and a power module 712 are also provided in the trolley base 701. The trolley control module 715 is electrically connected to an air pump 714, an air pump 718, a warning light 707 and a drive motor 713 respectively. The power module 712 is used to supply power to various components on the warning trolley 7.

[0078] In the above scheme, the vehicle control module 715 is located inside the vehicle body base 701. It is used to receive control command information and control the vehicle by controlling the corresponding execution unit. For example, after receiving the warning command information, it controls the drive motor 713 to drive the adjustment plate 705 to unfold, uses the air pump to inflate the unfolded airbag, uses the rotation drive mechanism to drive the stabilizing plate to be lowered to rest against the ground, and finally activates the warning light and voice broadcast module. The power module 712 is used to provide power to various components in the vehicle that require electrical energy, such as the air pump 714, the vacuum pump 718, the warning light 707, and the drive motor 713, etc. The side of the vehicle body base 701 is also provided with a charging base 703 that is electrically connected to the power module 712. When stored in the charging storage box 2, the charging base 703 docks with the charging unit in the charging storage box 2 to charge the power module.

[0079] In summary, the automatic high-speed vehicle malfunction warning device provided by this invention, when in use, involves several sets of warning trolleys 7 automatically moving to a preset distance in front of the accident site and connecting them in a row to form a warning protection zone. This warning protection zone not only warns oncoming vehicles, prompting them to take evasive action as early as possible to prevent secondary accidents, but also provides a certain degree of cushioning to the impact of colliding vehicles, reducing the impact force and thus providing a certain protective effect. Furthermore, after forming the warning protection zone, it will also provide a voice prompt to relevant personnel to move to the outside of the lane to avoid injury or death. The device provided by this invention, when in use, can achieve a good automatic warning effect, thereby reducing secondary accidents and improving safety.

[0080] like Figure 7 and Figure 8 Furthermore, the present invention also provides a method for automatic warning of high-speed vehicle malfunctions, characterized in that the method includes:

[0081] Step S101: Obtain highway traffic information to identify highway accident information;

[0082] Step S102: Obtain location information and image information based on the identified high-speed accident information and transmit them to the back-end service station;

[0083] In step S103, the back-end service station controls the nearest automatic warning device for vehicle malfunction on the highway to be activated based on the obtained location information, so as to connect several warning cars 7 into a row at a preset distance in front of the accident site to form a warning protection zone.

[0084] Step S104: Control the warning vehicle 7 to broadcast a preset voice prompt to remind personnel to evacuate to outside the highway guardrail.

[0085] In the above scheme, multiple cameras and other equipment deployed on the highway are used to acquire highway traffic information. The acquired information is then processed to automatically identify highway accident information. This accident information includes not only collisions but also breakdowns and parking situations. Then, image recognition technology and the location information of the cameras acquiring the accident information are used to make a comprehensive judgment to obtain location and image information, which is then transmitted to the back-end service station. The staff at the back-end service station dispatches relevant rescue vehicles to the scene based on the situation. Then, the nearest automatic vehicle breakdown warning device is activated to connect several warning cars 7 in a row at a preset distance in front of the accident site to form a warning protection zone. This ensures that safety warning operations are automatically deployed at the accident site before the rescue vehicles arrive, ensuring the safety of the scene and preventing secondary accidents. After deployment, a preset voice prompt will be played to remind people to evacuate to the outside of the highway guardrail.

[0086] In a preferred embodiment of the present invention, step S103, in which the background service station controls the nearest automatic high-speed vehicle fault warning device to be activated based on the acquired location information, so as to connect several warning cars 7 in a row at a preset distance in front of the accident site to form a warning protection strip, includes the following steps:

[0087] Step S1031: Drive several warning cars 7 to move to a preset distance in front of the accident site and line them up to block the lane where the accident vehicle is located.

[0088] Step S1032: Control the drive motor 713 to start and drive the threaded rod 716 to rotate, so that the threaded slide 717 rises and the two adjusting plates 705 are driven to unfold by the support rods 710 on both sides.

[0089] Step S1033: Control the air pump 714 to start to inflate the airbag 706 so that it expands;

[0090] Step S1034: Control the rotary driver to drive the rotating shafts on the front and rear sides of the vehicle body base 701 to rotate, thereby lowering the stabilizing plate 719 so that the side away from the rotating shaft rests against the ground.

[0091] Step S1035: Control the warning light 707 to start.

[0092] In the above scheme, the drive motor 713 drives the threaded rod 716 to rotate in the forward or reverse direction. With the cooperation of the vertical slide groove, the threaded slide block 717 can rise and fall along the length of the threaded rod 716. In this way, one end of the support rod 710 will also rise and fall with the rise and fall of the threaded slide block 717, and the other end can drive the adjustment plate 705 to open and close. When the warning operation is performed, it is opened, so that the permanent magnet strips on the adjustment plates 705 of the two adjacent trolleys will be attracted and fixed together to ensure the stability and integrity of the row of warning trolleys. On the one hand, it expands the warning area, and on the other hand, it can increase the stopping and buffering protection effect on vehicles or people. When not in use, the adjustment plate 705 is driven to close to reduce the overall volume of the warning trolleys, so as to facilitate storage in the charging and storage box for storage and charging operations.

[0093] In a preferred embodiment of the present invention, after the control warning vehicle 7 broadcasts a preset voice prompt to remind personnel to evacuate to outside the highway guardrail, the method further includes:

[0094] Once the accident has been handled, control all the warning trolleys 7 to move back to their original charging storage box 2 for charging.

[0095] In the above-mentioned scheme, there are often dangerous situations where people in the accident vehicle get out and stand next to the vehicle. This application controls the warning car 7 to broadcast a preset voice prompt to remind people to evacuate to a safe area.

[0096] In summary, when the automatic warning control method for high-speed vehicle malfunctions provided by this invention is in use, several sets of warning trolleys 7 automatically move to a preset distance in front of the accident site and connect the warning trolleys 7 into a row to form a warning protection zone. This warning protection zone can not only warn and remind oncoming vehicles to take evasive action as early as possible to prevent secondary accidents, but also buffer the impact of colliding vehicles to a certain extent and reduce the impact force, thereby playing a certain protective role. On the other hand, after the warning protection zone is formed, it will also provide a voice prompt to relevant personnel to move to the outside of the lane to avoid injury or death.
